Sensirion refines flow sensing dedicated to medical device sector

February 04, 2015 // By Graham Prophet
Integrated sensor specialists Sensirion has continued its development of devices targeting sepcific end-markets with a click-in design for disposable infusion flow sensing in medical applications.

This release represents a redesign of the company’s LD20-2000T disposable liquid flow sensor. With the goal of separating the core sensing element from other complex electronics, Sensirion has developed a two-piece, click-in design that radically improves the cost-efficiency of the solution while retaining high performance liquid flow measurement on a minimum footprint.

With the reduction of the disposable part to a bare minimum, Sensirion’s flow measurement solution is suitable for medical applications such as infusion pumps and catheters. In these applications, flow rates and monitoring of failure modes are essential to patient safety and the quality of the therapy. The click-in connection between the disposable sensor element and reusable part offers a quick and easy solution for communication and mechanical integration of the sensor. The click-in design illustrates the strength of Sensirion’s technology in providing small, cost-effective sensing solutions that offer high performance at low flow rates, typical of medical applications.

The use of intelligent, compact and cost-effective disposable liquid flow sensors will change the field of drug delivery, the company says, and enable solutions that are safer, more reliable and more mobile for care in hospital and at home. The Sensirion disposable liquid flow sensor is intended to allow manufacturers of medical devices to innovate new solutions using the technology.
